关于zemax中的近轴光线追迹
发现zemax中的近轴光线与我想的不太一样，它原文是这么说的 w5~j|c=_W
To ensure these features work properly, even for optical systems that do not meet the paraxial assumption above, Zemax traces “parabasal” rays which are real (real means using Snell's law explicitly) that make small angles with respect to a reference ray, which is usually an axis or chief ray. l 'wu-
cc_'Kv!
一直不明白这个“parabasal” rays是什么，它说是基于这种光线的真实光线追迹来得到的近轴光线追迹的数据 a|oh Ad
比如现在我的视场角是10，当光瞳坐标Px=0，Py=0的情况下（即主光线），为什么近轴光线追迹和真实光线追迹仍然有差别。
